Senior Functional Consultant

What You'll Do

The Senior Functional Consultant serves as the critical bridge between e-invoicing regulatory mandates, business processes, and technical implementation teams. You will translate complex global e-invoicing and transaction control (CTC) requirements into structured, applicable designs that ensure successful implementation across Avalara's E-Invoicing and Live Reporting (ELR) ecosystem. Working closely with mandate subject matter experts, engineering teams, ERP connector teams, implementation consultants, AI partners, and strategic technology partners, the Senior Functional Consultant ensures regulatory requirements are consistently interpreted, documented, and implemented. You will combine knowledge of Procure-to-Pay (P2P) and Order-to-Cash (O2C) processes with technical consulting and solution design capabilities. The Senior Functional Consultant is both a trusted advisor and implementation lead, helping accelerate customer onboarding, reduce deployment friction, improve implementation consistency, and promote successful customer outcomes.

• Translate regulatory mandates into standardized business and technical design artifacts.
• Create reusable implementation patterns, integration requirements, process flows, and solution blueprints.

• Analyze customer Order-to-Cash (O2C) and Procure-to-Pay (P2P) processes and identify impacts from e-invoicing mandates.

• Guide implementation teams (both internal and external), and integration teams through mandate-specific requirements and design decisions.
• Support onboarding and deployment activities for new ELR customers and partners.
• Provide consultation during project execution to ensure successful implementation outcomes.
